"All over this"?!? What do you expect them to do about it? ATC has reduced their risk and the risk of all the passengers by prohibiting them from flying in dangerous airspace.
You can avoid the ash cloud enroute, but not on departure or approach. Passengers can go via train to/from Italy or Greece if they "have to" travel.
This is, for once in the industry, a clear case of SAFETY FIRST!
